It's not that simple. To my knowledge, this problem goes back to the 1980s at least, and back then it wasn't Asian gangs. The excuses were the same. Social workers believed the under-age girls were entitled to a love life. Police thought they were slags. Nobody actually cared about them. Nobody did anything.

The ethnicity of the more recent perpetrators just provided another excuse. It wasn't the root cause of the inaction.
